Cutting Machine Thrust Bridge for Laminated Glass
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cutting machines for laminated glass sheets face difficulties in cutting sheets with high resistance intermediate layers, as the spacing between the glass pieces tends to reduce, making cutting challenging or impossible due to lateral or torsional deformations of the tubular body, even with increased pressure.
Innovation Solution
The cutting machine employs pressurizable tubular bodies made of elastomeric material with pre-deformation plates, which maintain a consistent spacing between glass pieces by varying fluid pressure within the tubular bodies, ensuring the thrust is directed orthogonally and maintaining the designed distance for accurate cutting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If increased pressure is applied inside the tubular body to maintain spacing, then the thrust force increases, but the crossbeam deflects upwards and spacing action does not improve
Solution Approach 1:
The patent changes the geometric parameters of the tubular body by introducing pre-deformation during manufacturing. The tubular body is pre-deformed to have a reduced initial diameter and stored elastic energy, which compensates for operational deflections and maintains precise spacing without requiring excessive pressure that would cause crossbeam deflection.
2Stability of the object's composition
If the tubular body is made more rigid to prevent deformation, then spacing stability improves, but the ability to accommodate high resistance intermediate layers is reduced
Solution Approach 1:
The patent uses a flexible tubular body made of elastomeric material that can deform to accommodate high resistance intermediate layers while maintaining spacing stability through pre-deformation. The flexibility allows the tubular body to adapt to varying resistance forces without losing its spacing function.
Solution Approach 2:
The pre-deformation of the tubular body creates stored elastic energy that acts as a cushion against operational variations and high resistance forces. This beforehand preparation allows the system to maintain spacing stability while adapting to different intermediate layer resistances.
3Manufacturing precision
If the crossbeam is fixed in position to maintain spacing distance, then manufacturing precision improves, but the system cannot adapt to varying intermediate layer resistances
Solution Approach 1:
The patent transforms the static fixed crossbeam system into a dynamic system where the tubular body can elastically deform in response to varying intermediate layer resistances. The pre-deformed tubular body maintains the designed spacing distance while dynamically adapting to different operational conditions through its elastic properties.
